God's work on the Cross through the sacrifice of Jesus Christ did not just pay the penalty for our sins, we died to sin. By the power of the Holy Spirit and the recreation of our spirit, we become a new creation -- no longer a slave to sin.
This is not to say we are not tempted, but God's Word assures us in 1Co 10:13, "There hath no temptation taken you but such as is common to man: but God [is] faithful, who will not suffer you to be tempted above that ye are able; but will with the temptation also make a way to escape, that ye may be able to bear [it]." God's Spirit within us will always whisper (in a strong voice), 'my child stop, go this way'.
Christians are never promised not to be tempted. The devil is the tempter (Mat 4:3). It is not to say that we won't fail -- we will -- because we are being perfected. Perfection is an on-going process of sanctification. But if we have the Spirit of God (are truly saved), we will abhor the sin and not return to it again and again, like a dog to his own vomit, or like a sow that's been washed to her own wallowing in the mire (2 Peter 2:22).
God has given us Jesus, His Spirit, and His Word. With the full armor of God (Eph 6:11), no Christian is enslaved to sin and is without excuse. Returning to the altar again and again, seeking forgiveness for a sin that hasn't been truly forsaken and given to God; is not a good testament of God's faithfulness - it is a testament however to 'walking in the flesh and not in the spirit' (Romans 8:1, 8:4).
David prayed in Ps 19:13 "Keep back thy servant also from presumptuous [sins]; let them not have dominion over me: then shall I be upright, and I shall be innocent from the great transgression." Intently sinning over and over, taking God's forgiveness for granted is the presumptuous sin that David is earnestly pleading with God to keep him from making.
Yes, born-again, Spirit-filled Christians can rest upon the promise of God that when we do fall into sin (very different from presumptuous sin), we can trust 1Jo 2:1 which says, "My little children, these things write I unto you, that ye sin not. And if any man sin, we have an advocate with the Father, Jesus Christ the righteous:"
Praise God for His enduring mercy! But praise Him even more that He has given us the spiritual might that comes from His Holy Spirit, empowering us to overcome any temptation, resist evil, and cause the devil to flee. We can rest not only in our promised salvation, but also in our deliverance! Amen!
